This is a 15-CD set and sheet music created primarily for shakuhachi accompaniment, featuring synthesized koto sounds. The CDs allow you to play along, creating the feeling of a real ensemble with koto and other instruments. They have been used on stage and are also great for visits to nursing homes and other similar settings. You can also achieve a rich and immersive performance by playing along with ocarina, flute, etc. There are over 290 songs, but I can't list them all here, so please refer to the photos. Please note that volumes 10 and 17 are missing from the track list. Price drastically reduced!!
